rkt through version 1.30.0 does not isolate processes in containers that are run with rkt enter. Processes run with rkt enter do not have seccomp filtering during stage 2 (the actual environment in which the applications run). Compromised containers could exploit this flaw to access host resources.
Weakness
The product performs an operation at a privilege level that is higher than the minimum level required, which creates new weaknesses or amplifies the consequences of other weaknesses.
